Volkswacht Bodensee - China to send fresh crew to Tiangong space station

The Shenzhou-18 mission -- crewed by three astronauts -- is scheduled to take off at 8:59 pm Thursday (1259 GMT) from the Jiuquan Satellite Launch Center in northwest China, Beijing announced Wednesday.

It will be led by Ye Guangfu, a fighter pilot and astronaut who was previously part of the Shenzhou-13 crew in 2021.

He will be joined by astronauts Li Cong and Li Guangsu, who are heading into space for the first time.

The latest batch of Tiangong astronauts will stay in orbit for six months, carrying out experiments in gravity and physics, as well as in life sciences.

They will also carry out a "project on high-resolution global greenhouse gas detection", Deputy Director General of the CMSA Lin Xiqiang said, according to state news agency Xinhua.

"All pre-launch preparations are on schedule," he said.

"They will work with other active astronauts to carry out the follow-up space station missions and to realise the country's manned lunar landing."

The Tiangong, which means "heavenly palace", is the crown jewel of a space programme that has landed robotic rovers on Mars and the Moon, and made China the third country to independently put humans in orbit.

It is constantly crewed by rotating teams of three astronauts, with construction completed in 2022.

The Tiangong is expected to remain in low Earth orbit at between 400 and 450 kilometres (250 and 280 miles) above the planet for at least 10 years.

The new crew will replace the Shenzhou-17 team, who were sent to the station in October.

- Moon by 2030? -

Plans for China's "space dream" have been put into overdrive under President Xi Jinping.

The world's second-largest economy has pumped billions of dollars into its military-run space programme in an effort to catch up with the United States and Russia.

Beijing also aims to send a crewed mission to the Moon by 2030, and plans to build a base on the lunar surface.

China has been effectively excluded from the International Space Station since 2011, when the United States banned NASA from engaging with the country -- pushing Beijing to develop its own orbital outpost.

China's space agency said on Wednesday it had secured new international partners for its planned lunar base, known as the International Lunar Research Station, which Beijing has said will be completed by 2030.

The partners include Nicaragua, the Asia-Pacific Space Cooperation Organization and the Arab Union for Astronomy and Space Sciences, Xinhua said.
